Durable 1" x 4" PVC toe nipple designed for Schedule 80 piping systems. This compact fitting features one threaded male pipe end (MPT) and one slip socket end (SLP), allowing a secure transition between threaded and solvent-weld connections. Ideal for irrigation and general PVC plumbing where a low-profile connection or offset is required.

  • Material: Schedule 80 PVC — high chemical resistance and increased wall thickness for demanding applications.
  • Connection: One threaded male (MPT) end for screw-in fittings; one slip socket (SLP) end for solvent welding with standard PVC cement.
  • Dimensions: 1" nominal diameter, 4" overall length; compact profile helps fit into tight spaces and toe-in assemblies.
  • Use cases: Made for irrigation systems, valve manifolds, pool and sprinkler plumbing, and other general-purpose water conveyance.
  • Installation: Apply PTFE tape or thread sealant to male threads; clean and prime slip socket before applying solvent cement per manufacturer guidance.

Supplied as PNIPO100-040. Available in single units; check variant stock for current quantities. Inspect fittings before solvent-welding to ensure a clean, secure bond. Schedule 80 construction provides extra strength for higher-pressure or exposed installations compared to Schedule 40 PVC.
